Shell casing with surface treatment



The patent file contains a single photograph executed in color. Copies of this patent with the color photograph will be provided by the Office upon request and payment of the necessary fee.

The sole FIGURE is a color photographic side elevation view of a shell casing with surface treatment showing my new design.

The shell casing is rotationally symmetric about its longitudinal axis so that the other side elevations views are the same as shown in the FIGURE. The ends of the shell casing do not form a part of the design. The design is the mottled purple surface treatment applied to a shell casing, and is not limited to the particular size and shape of the shell casing shown in the FIGURE. 

CLAIM The ornamental design for a shell casing with surface treatment, as shown and described.
